Shanghai Tower's 1,000-tonne tuned mass damper was seen swaying as Typhoon Bavi brought strong winds to the city.⁣ ⁣ Installed on the tower's 125th floor and suspended by 12 steel cables, the damper moves in the opposite direction of the building's motion to reduce wind-induced sway and improve stability during extreme weather.⁣ ⁣ #China #Shanghai #ShanghaiTower #TyphoonBavi #Typhoon #Architecture #Skyscraper
